FOLDING SUNSHADE Application filed March 12, 1982. Serial No. 598,368.

This invention relates to new and useful improvements in a folding sun shade.

The invention has for an object the construction ofa folding sun shade which is characterized by a plurality of panes of sun resistant glass adapted to assume positions acrossthe front of a window.

As a still further object of this invention it is proposed to provide means whereby the panes may be raised to a position above the window whenever desired.

As a still further object of this invention it is proposed to support the panes at inclinations and in a vertical row so that air may 5 easily pass between, them but the rays of the sun be limited to shine through the panes. As a still further object of this invention it is proposed to provide an awning located above the window into which the panes may be moved. 0

Furthermore, as another ob ect of this 1nvention it is proposed to provide a lazy tong structure associated with the panes into aof, reference will be had to the following description and accompanying drawing, and

to'the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompan-ymgdrawing forming a material part of this disclosure Fig. 1 is a front elevational view ofa folding sun shade, according to this invention,

mounted upon a window. 7

Fig. 5 is a fragmentary face view of a glass pane used in the'device.

Fig. 6 is a fragmentary view illustrating a modification.

Fig. 7 is a fragmentary front elevational view of Fig. 6.

Fig. 8 is a fragmentary sectional view taken on the line 8-8 of Fig. 6.

The folding sunshade, according to this invention, comprises a pair of vertical tracks 10 and 11 for attachment in opposite sidesof a window. These tracks are shown supported on opposite sides and to the front of a window 12. A plurality of sun-resist panes 13 of any suitable transparancy or color are arranged between the tracks 10 and 11. Each of the sun-resist paneshave end trunnions 14 projecting from opposite ends and slidably engaging the tracks 10 and 11. More particularly, each of the trunnions 14 engage in sliding members 15 which work within the tracks 10 and 11 which are in the form of channel members as clearly shown in Fig. 4:.

A lever 16 is pivotally mounted on each of the trunnions 14 on one of the ends of the panes 13 and is pivotally connected at its upper end 17 with the lower end of the upper adjacent pane and pivotally connected at its lower end 18 with the upper end of the loweradjacent pane. These levers are inv conjunction with the panes forming a lazy tong structure and serve to hold the panes 13 in a vertical row and in inclined positions. When viewed from the front the anes overlap was to make it impossible or the sun to shine through them but wind may pass between the panes since they are parallel to each other and spaced apart.

A means is provided for supporting the upper end of the lazy tong structure above the window. This means comprises a bar 19 attached between the upper ends of the tracks 10 and 11. A pair of crossed levers 20 are pivotally mounted upon the bar 19 andhave their lower ends respectively connected with P the upper end of the uppermost pane 13 and the upper end of the uppermost lever .16. The arrangement is such that the lower pane 13 may be raised to collapse the lazy tong structure above the window 12. The free endsof the levers 20 are in the shape of forks I A means is provided for collapsing the lazy tong structure -to aposition above the I window and comprises slide 22 attached upon the pinions of the lower pane'13 and threadedly engaging screws 23 rotatively supported within the tracks 10 and 11. These screws are connected for unison rotation by bevel gears 25 at the tops of the screws and upon the ends of a rod 26 rotatively supported in bearings 27 mounted upon the outside of the building. The lower end of one of. the screws 23 is provided with a bevel gear 28 in mesh with another bevel gear 29 upon a shaft 30 extended into the room of a house and equipped with a handle 31 to facilitate manual turning to cause the raising and lowerin'g of the lazy tong structure. An awning 32 is mounted above the window 12 and is adapted to house the folding sun shade in itscollapsed position above the window. This awning is formed with openings 33 to allow the passage of air so that on windy days it will be in a better position to restrain the damaging action of the wind.

In Fig. 5 the pane 13 is shown with apair of slots 13 having enlarged openings 13 for the insertion of the heads of any suitable trunnion to support the said pane,

In Figs. 6, 7 and 8 a modified form of the invention has been disclosed in which provisionis made for holding the panes at various diiferent inclinations relative to the lazy tong structure to adjust in the event of annoying light reflection from any of the panes. More particularly, each of the levers. 16 which are pivotally mounted upon the trunnions are also slidably arranged and urged towards the panes by coaxial spring 34 upon the trunnions acting between the track 10 and the lever. At the ends the lever '16 is formed with elongated'slots 35. in which pegs 36 are slidably mounted. These pegs have flanges 36' on opposite sides of the lever 16 so that they may not be withdrawn from the slots 35. The pegs 36 are engageable in one of a series of openings 37 formed in the sides of the panes which allows for the adjustment desired.

The operation of the device may be traced by assuming it in the position illustrated in Fig. 2. To raise the folding sun shade it is merely necessary to turn the handle 31 which causes the screws 23 to turn correspondingly and the followers 22 to movealong the screws and lift the lower pane 13. The motion will be transmitted by the lazy tong structure to all the panes and they will simultaneously assume a folded-position beneath the awning 32.

, trunnions and While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved'to' all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United.
